"...I just have an evil turn of mind..."

I knew that there was something I liked about you...

Now this is my idea of a survival item: they're waterproofed in a durable mylar type bag suitable for use as a drinking cup or to hold a multitude of items, they're high in fat for concentrated energy, and you can use 'em to start a conflagration if need be. It wouldn't surprise me if they even glowed in the dark. BTW, I love those crunchy cheesy little gutbombs.
